Patented `lune 14, 1932 UNT STATES FRANK H. KLE, OF CHCAGO, ILLINOIS METHOD AND BLANK FOR IPRODUCING FRAMES Application filed September 16, 1931. Serial No. 563,069.

rlhepresent invention relates tothe production of one piece frames for pictures, etc., and especially frames of the smaller type. I u t has heretofore been the practice to construct frames of small as well as large size of separate pieces of material, usually wood, secured together at the corners. rlhe main object of this invention is to simplify the manufacture of such frames and materially i reduce the cost thereof by producing a one piece frame of improved construction and devising a method of forming it which permits frames to be made rapidly and cheaply from readily available materials such as pressw' board, paper board, etc.

ln brief, the invention resides in produc-'- ing a one piece frame of improved design from librous material, which frame is pro- Y duced from blanks of material, such as common press-board, Which have been scored or cut in a certain novel manner, hereinafter disclosed, in the process of producing the complete frame therefrom. i l The frame and the method of producing it are described hereinafter and illustrated by the accompanying drawing, where:

Figure l is a rear view of a frame made according to this invention; Figure 2 is a section on the line 2-2 of Figure l;

Figure 3 is a front or face view of a blank cut in a manner to produce a plurality of frames of diminishing sizes;

Figure 4 is a composite view showing a section of the blank on the line 4-4 of Figure 3, with the inner portion displaced to the right as it appears after separation on the lines of the outermost cuts; Figure 5 is a front face view of a blank for forming a frame having an opening of irregular outline;

Figure 4, showing in section the final form of the frame after separation of the inner portion of the blank shown at the right.'

ln the practice of the invention there is used a section of press-board7 or like material, which, for purposes of illustration, is here shown in the several figures as rectangular. ln the process of producing a frame, or frames, from this section, it is scored or cut, on one side or face in the outline of the desired frame opening on the continuous line designated A (Figure 3). To save material and produce several frames from one section of board, additional cuts B and C, shown in Figure A3, outlining smaller frames, may also be made. @n the opposite side, the board is similarly cut, as indicated in dotted lines at A', Band C (Figure 3) but the cuts on that side are offset outwardly from the opposite cuts A, B and C. That is to say, the cuts which outline the openings in the respective frames inclose a greater area of board on one These cuts, which may be made with cutting dies, are gauged as to depth, so that they terminate in a common plane within the body of the board. The-blank thus formed is then ready to be separated to form the frame or frames. This separation is accomplished by pressing out the inner portion of the blank lying Within cuts towards the side on which the outline cut incloses the greater area, thus causing the material to tear or part on the plane in which the opposite cuts terminates, as indicated at l0 (Figure 4), thus forming there a shoulder or rabbet on the edge surrounding the picture receiving opening. In the case of the blank shown in Figure 3, this initial separation will produce the frame l1 shown in Figures l and 2. rlhe shoulder or rabbet l0 is preferably located at suflicient depth to permit it to receive the edges of a glass or the like, a picture, and then a cover piece which will lie substantially flush with the rear surface of the frame. The formation of this shoulder l0 is accordingly an important feature of the invention;

Where several frames are formed from one blank, as in Figure 3, the pressing out of the inner portions is repeated to form the succesiik longitudinal line of the grooves.

sive frames, but these Will be left With an outer flange or shoulder 12, Which can be cut away for better' appearance, if desired.

The frame of Figure 5 is formed essentially as above described. Here, however, the cut D, outlining the front of the opening, is of irregular outline, While the cut D on the opposite side is rectilinear. Separation is eifected by pressing the centra-l portion of the cut blank out towards the back or greater area side, 'thereby tearing the material apart in the terminal plane of the cuts to form a picture receiving shoulder of irregular area., but serving the same purpose as in the frame 11.

The modified frame of Figures 7 to 10 dilfer in that the blank is formed on the face which is to be the front of the frame With square cut grooves or kerfs 13 formed over the cut E. These grooves preferably intersect at the corners and extend to the edge of the blank, as in Figures 'T and 9, but that is largely for appearance. The grooves are so located as to bring the cut E in the central Upon separation of the portions of the blank on the lines of cut E and E (Figures 9 and 10), there will be formed a rear picture receiving shoulder 14 and, by reason of the grooves, a forwardly facing shoulder 15, which will give the appearance of a narrow mat surrounding the picture opening.

r will accordingly be evident from the foregoing disclosure that the invention involves a novel and simple method of producing one piece frame rapidly and cheaply from readily available materials, as is very desirable in the manufacture of the smaller types of frames suoli as used for photograph mounts, advertising novelties, etc., and that such frames may be produced in a variety of shapes and forms Without departure from the scope of the invention as defined in the following claims.

lVhat is claimed is:

1. rhe method of making frames from sections of press-board or the like which consists in cutting into one side of the board to a predetermined depth on the outline of the effective frame opening desired, similarly cutting the opposite side on an outline of greater area, and tearing apart the tWo portions of the board outlined by said cuts, thus producing a rabbeted edge in the material that joined the opposite cuts.

2. rihe method of making frames from sections of press-board or the like which consists in forming an endless cut of predetermined depth in each side of the board at predetermined distances from the edges thereof but at a greater distance therefrom on one side than on the other, with the cuts on the opposite sides terminating in offset relation in a common plane Within the body of the board and parallel to its surface planes, and

then removing that portion of the board lying Within the cuts by tearing it away on the terminal plane of the cuts.

3. The method of making frames from sections of press-board or the like Which consists in die cutting the opposite sides of the board in the contour of the frame opening desired, the cuts on the respective sides being gauged in depth so as to extend to a common plane Within the body of the board parallel to its surface planes, the area inclosed by the cut on one side being greater than on the other side, and then forcing out that portion of the board inclosed Within the cuts towards the greater area side.

4l. The method of making frames from sections of press-board or the like Which consists in die cutting the opposite sides of a section of board on the outlines of a plurality of frames With said outlines of decreasing area and cut one Within the other, the cuts on opposite sides of the board outlining each frame being in offset relation and eX- tending to a predetermined depth, and then separating the several frames by forcing out the successive portions outlined by the cuts towards the greater area side.

5. The method of making frames from sections of press-board or the like which consists in cutting into one side of the board to a predetermined depth on the outline of the eiii'ective frame opening desired, similarly cutting the opposite side on an outline of greater area, forming grooves in the face of the board along the line of the cut on the side of lesser area outline, and tearing apart the two portions of the board outlined by said cuts, thus producing a double rabbet in the edge surrounding the frame opening.

e. l blank for producing frames, consisting of a section of press-board or the like having cuts of predeteri'nined de th on its opposite sides formed on the out ine of the desired opening in the frame, said cuts inclosing a greater area on one side of the board than on the other.

7. A. blank for producing frames, consisting of a section of press-board or the like having grooves formed in one face on lines coinciding with the frame opening desired and having a cut of predetermined depth formed in the bottom of said grooves on the central longitudinal lines thereof along which cut the material is severed in forming the frame.
